MA'P-CASE.

SPECIFICATION forming part of Letters Patent No. 273,059, dated February27, 1883.

Application filed August 8, 1882. (No model.)

To all whom it may concern:

Be it known that I, HENRY B. FRY, of the county of Grant and State ofIndiana, have invented certain lmprovements in Map- Cases, of which thefollowing is a specification.

The object of this invention is to produce an apparatus whereby a seriesof maps may be inclosed and protected in a compact form and either onein the series extended and exposed to view at will. It is the specialaim of the apparatus to avoid the occupation of floorspace and to admitof the maps being suspended vertically against a wall or over thesurface of a stationary blackboard. The apparatus consists of a case orsupport, aninternal roll having a series of maps suspended therefrom, acrank or manual operating device, and a detent or brake; and theinvention consists in the peculiar features and combinations hereinafterspecified.

Referring to the accompanying drawings, Figure 1 represents a verticalsection through my apparatus, with one of the maps extended in positionfor use. Fig. 2 is a section of the same, illustrating the manner inwhich the maps are brought successively into an exposed position. Fig. 3is a vertical cross-section on the line 3 y, Fig. 4, showing the brakeor friction device by which the rotation of the roll is controlled. Fig.4. is a view showing the case in vertical section on the line m a, Fig.1, and the roll and maps thereon in elevation.

Referring to' the drawings, A represents a case or cabinet, which may beof anysnitable form, with one flat side provided with eyes a orequivalent means, whereby it may be suspended firmly in position againstthe wall. The case is in the present instance made in a quadrantal formand provided with two doors or lids, b and o, hinged to the top andbottom, respectively, and extending the entire length of the case forthe purpose of giving access to the interior of the same.

13 represents a horizontal roll, extended lengthwise within the casefrom end to end thereof, the roll having a journal at one end seated inaremovable slide, 01, while at its opposite end it has ajournal extendedthrough the end of the case to the outside, and there provided with ahand-crank, O, by means of which the roll may be revolved at will. Theslide d is seated removably in guides or sup- B in any suitable manner,the mode of attachment being preferably such that they may bedisconnected at will. The sheets are made of such length or so disposedwith relation to each other that when unwound from the roll andpermitted to hang downward the edge of each sheet will extend below theedge of the sheet next in front. To the ends of the maps, all of whichare thus exposed to view at one time, I apply names, numbers, or theirequivalents, to designate the particular maps upon the concealed faces.To thelower end of each sheet I usually apply a transverse bar or stripof wood, i,' which serves the twofold purpose of holding the sheet in anextended position and of serving as a weight to facilitate theseparation and manipulation of the edges of the sheets as they arepassed over the top of the roll.

E represents a friction brake or detent, located within the case andacting upon one end of the roll to limit its rotation and hold it in anyposition in which it may be placed. This brake may be of any suitablecharacter, the arrangement represented in the drawings consisting of anarm or lever pivoted at one end in the case and hearing atits middleupon the roll, and connected at its opposite end to a spiral spring, g,which is attached .to a fixed stud.

particular map-for example, that of Asia revolves the roll until the endof that map is presented on the front of the roll, whereupon he graspsthe ends of those maps which may be exposed above it and pushes thembackward over the top of the roll, permitting them to fall on the rearside. He then turns the roll backward, the effect of which is to lowerthe map of Asia below the case and expose its entire surface to view. Byrepeatiu gthis operation either map in the series may be exposed atwill. When the map is no longer required the roll is again turned andthe entire series of maps wound up.- on the same within the case, wherethey will be caused to remain by the action of the brake holding theroll in position. After being thus wound, the closing of the cabinetwill serve to protect the maps from dust and insects.

If desired, maps may be applied on both surfaces of each sheet, in whichcase, however,

the two ends of the roll will be made alike in form, so that the rollmay be removed and turned end for end within the case to expose eithersurface on the front at will.

It will of course be understood that the form of the cabinet, the formof the brake-or detent, and the construction of the bearings whichpermit the roll to be removed may be modified at will. 4

If preferred, the slide d may be omitted and the end of the roll merelydropped into a fixed hearing which is open on the upper end.

I am aware that in devices for exhibiting, wall-paper portable stands orframes designed to rest upon the floor have been provided with largecylinders having a series of small sheets attached thereto in differentpositions, the parts being; constructed in such manner that severalsheets were exposed at one time upon an inclined table or supportprovided for the purpose. This I do not claim.

I am aware that a roll has been provided with a series of maps, andcombined with a second roll or pressure device, arranged to act abovethe main roll upon the maps for the purpose of holding them in positionwhen wound upon the roll, and of releasing their My arrangement difi'ersends successively.

from that above cited in the important feature that the ends or" themaps are weighted and left entirely free, the usual upper roll orpressure device being dispensed with, thus leaving the ends of the mapsfree to pass in both directions. In this manner I am enabled to simplifythe construction, reduce the cost, and secure the instantaneous exposureof any particular map required, while leaving the maps free to hang in avertical direction.

The present invention is restricted to those matters and things whichare hereinafter claimeti; and as to all matters which may be describedor shown, but which are not claimed, the right is reserved to make thesame the subject of a separate patent.

Having thus described by invention, what I claim is- 1. As a new articleof manufacture, a suspension device for exhibiting maps in series,consisting of an external case provided with a door in its bottom, aroll mounted in said case, a handcrank for rotating said roll, and aseries of maps all suspended at one end from said roll with their lowerends terminating at different heights.-

2. in a map-exhibitor, the combination of the case A, having two doors,Z) and r, the horizontal roll, the friction-brake, the crank, and theseries of maps suspended from the roll with their lower ends atdifferent heights.

3 In a map -exhibitor, a suspension case provided with an internal rollhaving a series of maps wound thereon, in combination with means,substantially as described, for closing the bottom of said case andpermitting the same to be opened to allow the descent of the maps.
